Very easy. Never done it with an Orion, but I have with a few MDX's. No need to change anything in ProGrammer. Just get the kit (hope you have good luck or deep pockets) and swap it over. Here's a brochure with info and model numbers on the remote-mount kit. Like I said, these aren't exactly falling out of trees...but with enough searching you might get lucky. Or just get out the checkbook and call up Harris.
